MACHINE FOR STRINGING BLANKS.

SPECIFICATION forming part of Letters Patent No. 745,389, dated December 1, 1903.

Application filed November 8, 1901. Serial No. 81,644. (No model.)

To aZZ whom it may concern.-

Be it known that I, JAMES H. RUSSELL, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Machines for Stringing Blanks, of which the following is a specification.

The present invention relates to improvements in machines of the type mentioned which have a head and fingers for shirring the blank and also have needles that are passed through the head and blank inorder to receive the strings from suitable devices and draw them through the blank.

Objects of the invention are to improve the operation of such machines and to obviate arranged string-holders 14, pivoted, as at 15,

certain defects and disadvantageous features which hitherto existed in them, to provide against breakage of the latches of the neodles, to provide for renewal of the needles, to simplify and improve the string holding and delivering mechanism, and to relieve the'operator in manipulating the strings.

To these and other ends hereinafter set forth the invention, stated in general terms, comprises the improvements hereinafter described and claimed.

The nature, characteristic features, and scope of the invention will be more fully understood from the following description, taken in connection with the accompanying drawings, forming part hereof, and in which Figure 1 is a sectional view of a machine embodying features of the invention. Fig. 2 is a top or plan View of the same, and Fig. 3 is a transverse sectional view taken on the line 3 30f Fig. 1. Fig. 4 is a plan view of a portion of a cam-rod 30.

In the drawings, 1 represents ways upon which the hook 2 reciprocates. As shown, the ways comprise parallel rods supported by standards 3 and by the framework 4:, that carries the folders 5 and folder-head 6, and the shank of the hook is provided with openings which slide upon these rods; The"m0 tion of the hook is therefore a rectilinear one in a horizontal plane. The rocker-arm 7 has slot-and-pin connection with the hook, and it is suitably pivoted to the base of the machine. As shown, the rocker-arm 7 is made in two parts, each part being arranged upon the outside of the shank of the hook, and at the base the two parts are connected by a transversely-ranging crank-pin 8 and are separately pivoted, as shown in Fig. 3.

9 is a spring which tends to shift the rocker arm and hook into the position shown in Fig. 1.

To the framework of the folder-head is pivoted the finger 10, which is notched, as at 11, for engagement with a string, as will be hereinafter described. The finger 10 is provided with a cam projection 12, and it is acted upon by a spring, as 13, which tends to shiftit into the position shown, in which it rests uponits back-stop 21. I

Upon the top of the machine, Fig. 2, are

and provided at their ends with split pins 16.

17 is a spring which tends to shift the string-holders into engagement with their back-stops 18. The string-holders therefore are spring-actuated and are capable of motion within limits.' Their purpose will be hereinafter described fully; but it is to facilitate the operator by relieving him from the necessity of manipulating the string during a part of the operation. The-folders, which occupy positions on the outside of the folder-head, are provided with openers and closers 19 for the latches 20 of the needles. These openers and closers 19' comprise bladespivoted to the folders and afford a range of motion between stops 27. The blades or openers and closers 19 are notched, as at 22, in vertical alinement with the openings in the folders through which the needles are to pass, and they practically cover these openings, so as to insure their engagement with the needlelatches. Of course they leave enough of the openings uncovered to enable the needlepoints to enter. These notches are made for the purpose of allowing the points of the neodles to properly penetrate the folders. The purpose of the openers and closers is for those on the right to insure the proper opening of the latches when the needles. are proceeding toward the left to receive the string and for those on the left to insure the proper closing of the same when they are proceeding toward the right with the 'string. The de- IOO - This affords a convenient and reliable means shifted toward the left.

for holding the needles and for permitting of their convenient renewal. The slide or part 26 is arranged to slide backward and forward horizontally, and it is. shifted by means of the hand-lever 27 through the intervention of a link 28 or in any other suitable way. The part 26 is fitted with a bracket 29, which carries the needle-holder and works back and forth in a slot in the top of the machine. The part 26 also carries a cam-rod 30, guided in the framework of the folder-head and fitted with a cam 31, that cooperates with the cam projection 12, so as to lift it from its backstop 21 and turn it so as to elfectthe required movements of the finger 10. The cam-rod 30 when viewed in plan, Fig. at, is seen to have an enlarged end a, which serves to open the folders, as will be hereinafter described. The slide 26 also carries a rod 32, guided by suitable brackets and having its end 33 pointed, so as to close the folders. This rod 32 is also fitted with a part or knife-cam 34, having a slot 35, which engages the crank-pin 8.

Having thus described the principal features of construction of the machine, its mode of operation, as well as certain other features of construction, maybe described as follows: lVhen the parts are in the positions shown in the drawings, a suitable blank is placed over the folder-head and, if necessary, supported by the rod 36. The handle 27 is then shifted, with the result that the slide 26 is moved toward the left in Fig. 1. This motion of the slide causes the needles, the cam 31, the part 33, and the slot 35 to be As the needles pass under the openers on the faces of the righthand folders the openers serve to positively open the latches. The part 33 serves to close the folders in onto the folder-head, thus, as it were, fluting the blank, so that the needles pass through the flutes. The cam 31 runs under the projection 12 and throws the finger 10 toward the right, and the notch or groove 35 engages the crank-pin 8 and slides the hook 2 toward the right on its straight horizontal Ways. with its ends in the split pins 16 and its bight around the fingers 10 and in engagement with the hook 2. It also lies in the hooks of the needles whose latches are open; but it bears upon the fingers 10 rather than on the hooks of the needles, because the latter are not well adapted to bear the strain, which at the commencement of the return movement of the handle 27 is considerable and which is borne,

The string is then placedceases as has been said, by the fingers l0. When the notches 11 are present, the string passes over them. As the handle 27 is returned to its original position the book 2 is moved by the cam 35 toward the left, and thus draws the bight of the string toward the left and pulls the string-holders l t inward, the strain being taken by the fingers 10, which are properly positioned and held for resisting it by the cam 31. As the return motion of the handle 27 continues the ends of the string pull out of the parts 16. The hook 2 is freed from theinfluence of the cam 35 and is brought under the in fluence of the spring 9, which is comparatively light, so that the hook assumes a position more or less midway of its travel and finally moves up toward the right. Du ring this time it is substantially regulating the tension and is drawn along toward the right by the pullof the needles on the string. During this time and while the hook is under the influence of the spring 9 the cam 31 has released the fingers 10, so that they come into the position shown in the drawings; but when.

this occurs they have done their work in taking the initial pull of the hook on the string from the needles. It is to be understood that when the hook is under the influence of the spring 9 the needles can easily sustain the pull which they exert on the string. As the handle 27 is thus being returned to its initial position the part (L of the rod 30 serves to open the folders in order to permit of the removal of the blank in which the string has been inserted. It will be understood that when the blank is removed from the folder-head the bight of the string is lifted off the hook 2. Before the needles reach the blank the closers 19 on the left-handfolders serve to positively close their latches. In the finished blank as it leaves the machine the bight of the string projects on one side and the two free ends of the string project on the other side.

It will be obvious to those skilled in the art to which the invention relates that modifications may be made in details without departing from the spirit thereof. Hence I do not limit myself to the precise construction and arrangement of parts hereinabove set forth, and illustrated in the accompanying drawings; but,

Having thus described the nature and objects of the invention, what I claim as new, and desire to secure by Letters Patent, is
